Improvements to Your Commute

Under the U.S. 322 (Conchester Highway) Improvement Project, PennDOT is adding new, adaptive traffic signals to intersections along the project corridor.

According to the Federal Highway Administration (FHWA), poor traffic signal timing contributes to traffic congestion and delays. Conventional signal systems in place along U.S. 322 (Conchester Highway) and elsewhere use pre-programmed, daily signal timing schedules to trigger traffic signal cycles. However, adaptive signal control technology adjusts the timing of red, yellow, and green lights to accommodate changing traffic patterns and ease traffic congestion.

The main benefits of adaptive signal control technology over conventional signal systems are that it can:

  • Continuously distribute green light time equitably for all traffic movements
  • Improve travel time reliability by progressively moving vehicles through green lights
  • Reduce congestion by creating a smoother flow
  • Prolong the effectiveness of traffic signal timing

There are many alternatives to driving alone, including taking transit, ride-sharing, alternative work schedules, working from home, and more. PennDOT and the Delaware Valley Regional Planning Commission (DVRPC) have teamed up to help you find the best way to get to work during construction and after.

Our region's Transportation Management Associations (TMAs) are administering components of the DVRPC's Mobility Alternatives Program (MAP) that will help employers and employees find creative ways to get to work on time and back home again. Contact the Delaware County TMA if your work site or commute is in Delaware County, or click here to find the TMA where your work site is located.
